中文摘要

本文提出了耦合带状线微电感的损耗模型,重点分析了占空比和相移角对谐波电流幅值及电感效率的影响,并探讨了单磁芯双绕组高耦合系数的作用。该模型为高频功率变换器的磁性元件设计提供了理论参考。

English Abstract

In this paper, models that account for the duty cycle and phase shift angle of the applied phase voltages in coupled stripline microinductors are presented and are shown to have a significant impact on harmonic current amplitudes and therefore microinductor efficiency. The impact of a high coupling factor between two windings surrounded by a single core is also investigated. The models are validat...
